Boil the pasta- Begin by filling a large pot with water and adding a generous amount of salt. Allow the water to come to a rolling boil before adding in the tagliatelle pasta. Cook according to package instructions until perfectly al dente, then drain and set aside.

Prepare the sauce - In a large skillet or pan, melt a generous amount of butter over medium heat. Once melted, add in freshly minced garlic and sauté for approximately two minutes until the aroma fills your kitchen. Gradually sprinkle in all-purpose flour, stirring constantly to avoid any pesky lumps. Slowly pour in heavy cream while whisking continuously for a smooth and creamy consistency. Cook for an additional two minutes as the sauce thickens to perfection.

Add veggies and protein - Gently stir in the colorful combination of diced bell peppers and canned jalapenos, cooking for approximately three minutes until the peppers reach the perfect level of tenderness. Then, introduce your choice of cooked chicken to the mix, stirring well and allowing it to heat through.

Combine and coat - Using tongs, gently combine your cooked tagliatelle pasta with the flavorful and creamy sauce in your skillet. Ensure each noodle is evenly coated before sprinkling in salt and pepper to taste. Continue cooking for an additional two minutes until all ingredients are heated through.

Serve and garnish - Transfer your delicious Rattlesnake Pasta onto serving plates or bowls, ensuring each plate receives a generous helping of cheese grated right on top. Finish off with a few extra slices of jalapeno for an added kick and beautiful garnish.
